Definitions
- the invention relates to a lamp with a plate-shaped light guide element.
- Fig. 14 shows a perspective view of such a lamp in the form of a ceiling lamp at an angle from above.
- the light comprises a horizontally oriented plate-shaped light guide element and an LED light source (LED: light-emitting diode).
- LED light-emitting diode
- a light emitted by the LED light source enters the light-guiding element at the edge and finally exits the light-guiding element at the bottom.
- a downward light emission of the luminaire can be achieved, which is usually used to generate direct lighting.
- the openings 100 are characterized by a reduced light emission, that is to say as dark spots. This generally undesirable effect cannot be satisfactorily resolved even by using a diffuser film.
- the invention has for its object to provide a corresponding improved lamp.
- the luminaire should be suitable for generating direct and indirect lighting and should have a downward, uniformly bright light-emitting surface.
- a lamp which has a plate-shaped light-guiding element with a first large surface area through which one Level is set. Furthermore, the light-guiding element has a second large surface area, opposite the first large surface area, by means of which a further plane is defined, and a narrow edge area area, by means of which the second large surface area is connected to the first large surface area. A first side is separated from a second side by the plane, the second large surface area being on the second side of the plane. Furthermore, the luminaire has an LED light source with LEDs for emitting light, the design being such that the light at least partially radiates into the light-guiding element via the edge area and furthermore the light-guiding element again via the second large surface area to achieve direct illumination leaves.
- the luminaire comprises an elongated light guiding element with light openings, which extends along the edge surface area, the design being such that a portion of the light shines to the first side and thereby shines through the light openings to achieve indirect lighting, the light guiding element continuing to hold the LED light source is designed.
- the light-guiding element can be used to emit the light in a particularly suitable manner in order to achieve indirect lighting. It is also particularly suitable to provide a larger amount of light for indirect lighting.
- the fact that the light guide element is also designed to hold the LED light source means that a corresponding separate component can be saved.
- the light openings can be provided closer to the edge of the light-guiding element than the corresponding openings in the reflecting plate; this is particularly advantageous because it enables a fundamentally higher degree of efficiency to be achieved.
- the light guiding element is preferably also designed to hold the light guiding element. This is advantageous because it makes it possible to dispense with a separate component for holding the light-guiding element.
- the LED light source is preferably held in position by the light guide element such that the LEDs are located between the plane and the further plane, preferably centrally between the plane and the further plane. This enables a particularly suitable distribution of the light to achieve direct lighting on the one hand and indirect lighting on the other.
- a particularly good control of the light to achieve indirect lighting can be achieved if the light openings are designed as reflectors.
- the light guide element preferably has a flange region, which extends on the second side of the plane and parallel to the plane, for holding the light guide element.
- a flange region which extends on the second side of the plane and parallel to the plane, for holding the light guide element.
- the luminaire preferably also has a housing with housing openings which are designed in such a way that the portion of the light which shines through the light openings of the light guide element also at least partially shines through the housing openings of the housing. In this way, the luminaire can be suitably protected with advantageous optical properties.
- a distance is preferably formed between the edge surface area and the LEDs, so that part of the light does not fall into the light-guiding element. In this way it can be achieved that a particularly large amount of light is available for indirect lighting.
- the design is preferably such that the part of the light that does not fall into the light guide element at least partially shines through the light openings. In this way, indirect lighting can be specifically shaped.
- the edge area is preferably positioned so close to the LEDs that practically all of the light shines into the light-guiding element.
- the light-guiding element preferably has a surface structuring through which part of the light radiated into the light-guiding element is directed towards the light openings of the light-guiding element. In this case, the amount of light can be suitably increased to achieve indirect lighting.
- a luminaire which has a plate-shaped light-guiding element with a first large surface area, through which a plane is defined. Furthermore, the light-guiding element has a second large surface area, opposite the first large surface area, by means of which a further plane is defined, and a narrow edge area area, by means of which the second large surface area is connected to the first large surface area. A first side is separated from a second side by the plane, the second large surface area being on the second side of the plane. Furthermore, the luminaire has an LED light source with LEDs for emitting light, the design being such that the light at least partially radiates into the light-guiding element via the edge area and furthermore the light-guiding element again via the second large surface area to achieve direct illumination leaves.
- a distance is formed between the LEDs and the edge area, so that a portion of the light does not fall into the light-guiding element and shines on the first side of the plane in order to achieve indirect lighting. In this way, a particularly large amount of light is available for achieving indirect lighting.
- the lamp in the form of a pendant lamp or a ceiling lamp is particularly suitable.
- Fig. 1 shows in a cross-sectional sketch an edge region of a light emission arrangement of a lamp according to the application according to a first embodiment.
- Fig. 2 shows a perspective view of this from obliquely above and the Figures 3 and 4th corresponding exploded views.
- the light-emitting arrangement comprises a plate-shaped light guide element 1 with a first large surface area 2, a second large surface area 3 opposite the first large surface area 2 and with a narrow edge area area 4, through which the second large surface area 3 is connected to the first large surface area 2 is.
- the light-guiding element 1 is aligned with respect to the vertical such that the first large surface area 2 is oriented horizontally and thereby points upwards and the second large surface area 3 downwards.
- This orientation is preferred for the operation of the luminaire, but in general a different orientation can also be provided for the operation, for example a slightly oblique orientation of the light guide element 1.
- the first large surface area 2 defines a plane E1 - here a horizontal plane - and the second large surface area 3 defines a further plane E2, which is preferably oriented parallel to the first-mentioned plane E1.
- a first side S1 which here corresponds to the upper half-space, is separated by the plane E1 from a second side S2, which here corresponds to the lower half-space. Consequently the second large surface area 3 is located on the second side S2 of the plane E1.
- the light-guiding element 1 has a rectangular shape overall, so that the two large surface areas 2, 3 mentioned are correspondingly rectangular in shape.
- the shape of the light-guiding element 1 thus forms four rectilinear edge regions, the edge surface region 4 extending along one of these four edge regions, preferably over the entire length of the corresponding edge region.
- the light-emitting arrangement furthermore comprises an LED light source 5 with LEDs 6 for emitting a light, the design being such that the light at least partially radiates into the light-guiding element 1 via the edge area 4 and furthermore the light-guiding element 1 via the second large surface area 3 leaves again for direct lighting.
- the LEDs 6 are preferably - as in FIG Fig. 4 outlined - arranged along a horizontal straight line extending between plane E1 and the further plane E2.
- the LEDs 6 can be arranged on at least one elongated circuit board 15, which is arranged to extend parallel to the edge area 4.
- the LED light source 5 preferably extends over the entire length of the edge surface area 4, so that the light emitted by the LEDs 6 radiates into the light guide element 1 along the entire edge surface area 4.
- the board 15 is preferably oriented vertically; this results in a particularly good irradiation of the light in the light guide element 1.
- the LED light source 5 also has a connection element 16, for example in the form of a socket, on the circuit board 15, on a side opposite the LEDs 6, which is used for connection to a current source for the electrical supply of the LEDs 5 is designed.
- the connection element 16 is preferably arranged on an end region of the circuit board 15, as sketched in the figures.
- the light-emitting arrangement comprises an elongated light-guiding element 7 with light openings 8 extending along the edge surface area 4.
- the light-guiding element 7 is preferably so long that it extends along the entire edge surface area 4.
- the design is such that a portion of the light shines towards the first side S1, here upwards into the upper half-space, and shines through the light openings 8 in order to achieve indirect lighting.
- the light openings 8 preferably have an extension which is “orthogonal” to the light guide element 1 - here upwards.
- a light opening 8 is provided for each of the LEDs 6, it can be achieved that a particularly large amount of light is emitted upwards. However, it can also be provided that no light opening 8 is provided for part of the LEDs 6, that is to say, for example, viewed along the row of LEDs 6, only for every second or every third or every fourth LED 6 and. s. w., then it can be achieved that correspondingly less light is emitted upwards.
- a light opening 8 is provided for each LED 6, a common light opening 8 serving for two adjacent LEDs 6.
- the light openings 8 can be designed as reflectors for this purpose.
- the light openings 8 can be delimited by vertically extending wall areas 17, which are preferably at least partially reflective, in particular highly reflective.
- the light guide element 7 is functionally advantageously designed to hold the LED light source 5.
- a snap-in connection is provided to hold the LED light source 5 on the light guide element 7 in a manner that is easy to assemble.
- the light guide element 7 can have latching extensions 18 for this purpose, which engage in correspondingly designed latching recesses 19 which are formed on the LED light source 5, for example on the circuit board 15.
- the light guide element 7 has a carrier region 20 which is designed to support the LED light source 5.
- the LED light source 5 - here with the circuit board 15 - rests on the carrier region 20.
- the light-guiding element 7 preferably has a vertical wall region 21 which on the one hand extends upwards beyond the plane E1 and there contributes to the formation of the light openings 8 and on the other hand extends downwards beyond the plane E1, in this region below the Level E1 of the support area 20 extends from the wall area 21.
- the light guide element 7 is preferably also designed to hold the light guide element 1.
- the light guide element 7 can have a flange region 9, which extends on the second side S2 of the plane E1 or below the plane E1 and extends parallel to the plane E1.
- the flange region 9 preferably extends over the entire length of the light guide element 7.
- the configuration is preferably such that the flange region 9 is located vertically below the light openings 8.
- the design is also particularly preferred such that the light openings 8 are located entirely within a projection of the flange region 9 which is normal with respect to the plane E1. In this way, it can be avoided that dark areas can be seen when looking at the light guide element 1 from below at those points at which light shines through the light openings 8 upwards. This is in particular an advantage over the prior art mentioned at the outset.
- the flange area 9 is configured opposite the support area 20 with respect to the vertical wall area 21.
- the flange region 9 and the carrier region 20 preferably form an outer surface 22 of the light guide element 7 pointing downward, which preferably extends flat and preferably horizontally.
- the design is preferably such that the LED light source 5 is held in position by the light guide element 7 such that the LEDs 6 are located between the plane E1 and the further plane E2, in particular in the middle between the Level E1 and the further level E2.
- This is also the perspective sectional view of the Fig. 6 can be seen in which, in addition to the light emitting arrangement, a housing 10 of the lamp is also shown.
- the light openings 8 are preferably covered with a translucent element, for example by a diffuser film or by a lens.
- the light openings 8 can each be covered individually with a corresponding element, but alternatively a correspondingly continuous element can also be provided which covers all light openings 8. This design prevents dust from entering the light openings 8.
- the light radiating through the light openings 8 can be optically influenced.
- the housing 10 has, as in Fig. 5 outlined by way of example, preferably housing openings 11 which are designed in such a way that the portion of the light which shines through the light openings 8 of the light guide element 7 also at least partially shines through the housing openings 11 of the housing 10.
- the housing openings 11 are designed as vertical extensions of the light openings 8. The light can thus suitably radiate upwards out of the housing 10 and generate the desired indirect lighting.
- FIG. 9 and 10 is a lamp according to the application shown in the form of a pendant lamp, wherein in Fig. 10 a corner area is shown in more detail.
- the shape of the lamp is essentially determined by the shape of the light-guiding element 1.
- the luminaire also has a rectangular shape overall, so that four rectilinear edge regions 31, 32, 33, 34 are formed.
- the LED light source 5 is formed on a first edge region 31 of the four edge regions 31, 32, 33, 34.
- the row of housing openings 11 extends over the entire length of the relevant edge region 31.
- An analog design can be provided on a second edge area 32 opposite the first edge area 31, so that light also shines into the light-guiding element 1 here and on the other hand also radiates upwards to produce the indirect lighting. All four edge regions 31, 32, 33, 34 can also be designed in accordance with the above description.
- Ropes 35 can be used to suspend the luminaire, a low-voltage power supply for the LED light source 5 preferably being provided via these ropes 35.
- the light-emitting arrangement is particularly suitable for the design of a flat "area light".
- a distance a can be formed between the edge area 4 and the LEDs 6, so that part of the light does not fall into the light-guiding element 1.
- the design is such that the part of the light that does not fall into the light-guiding element 1 at least partially shines through the light openings 8.
- the design can be such that the distance a is greater than the distance ⁇ between the plane E1 and the further plane E2, preferably greater than one and a half times the distance ⁇ , particularly preferably greater than twice the distance ⁇ .
- the distance a is preferably selected to be so large that the flange region 9 does not appear to be too wide.
- the distance a is less than four times the distance ⁇ , particularly preferably less than three times the distance ⁇ .
- a reflector element 23 with an upward-facing, in particular horizontal, planar reflecting surface is preferably arranged between the LEDs 6 and the edge surface region 4 below the LEDs 6, by means of which rays L1 of the light are directed into the light-guiding element 1 via the edge surface region 4 and further rays L2 of the light are deflected such that they subsequently pass through the light openings 8.
- the reflector element 23 is preferably designed and arranged in such a way that the reflecting surface extends at least to a first approximation in the further plane E2. Still further rays L3 of light can pass through the light openings 8 without prior interaction with a surface of a component of the luminaire.
- the edge area 4 should be positioned so close to the LEDs 6 that practically all of the light shines into the light-guiding element 1.
- the light-guiding element 1 has a surface structuring 40, for example in the form of a roughening, through which part of the light radiated into the light-guiding element 1 is directed toward the light openings 8 of the light-guiding element 7.
- the advantageous light emission can be achieved upwards of indirect lighting can also be achieved without the light guiding element 7.
- the proportion of light that is directed upwards to achieve indirect lighting can be selected within a large range, that is to say “set” very well, so to speak. Values of less than 1% up to over 90% can be achieved for this proportion.
- the proportion can be suitably made larger or smaller by the choice of the size and / or density of the light openings 8; This can also be influenced by selecting the distance a.
- the size of the portion can also be varied well by means of corresponding coupling-out structures, such as the surface structuring 40 mentioned above.
- the lamp according to the application can, for example - be designed as a pendant lamp, as shown, but it can also be designed as a ceiling lamp.
- a more intensive upward light emission is desirable in the case of a pendant lamp, and a lower upward light emission in the case of a ceiling-mounted luminaire.
- a surface-mounted luminaire only a "light aura" is created by the light emitted upwards. Accordingly, it is advantageous to provide more and / or larger light openings 8 in the case of a pendant lamp than in the case of a ceiling-mounted lamp.
- the lamp is also suitable, for example, in the form of a floor lamp or a wall lamp or basically as a lamp which is used to achieve indirect lighting.
- At least one further optical element 41, 42, 43, 44 can be provided above and / or below the light guide element 1.
- a diffusion film and / or an optical element with prism structures can be arranged below the light guide element 1 and a reflector and / or a hollow web plate can be arranged above the light guide element 1.
- the flange region 9 makes it possible for a viewer who is looking at the lamp from below to not be able to see those places where the proportion of the light is deflected upwards. Therefore, in comparison to the prior art mentioned at the outset, it is also not necessary to use a diffuser film in order to “hide” the relevant points. This is particularly advantageous, because without such a diffuser film it can be achieved that the luminaire, when viewed from below, allows a clear view of a rear reflector and thus appears particularly brilliant. In addition, the absence of a corresponding diffuser film enables an increase in efficiency.
- Fig. 11 1 shows a perspective sectional sketch of an edge region of a light emitting arrangement according to the application with a heat sink 50
- Fig. 12 shows a corresponding exploded view.
- the circuit board 15 is preferably positioned between the heat sink 50 and the light guide element 7.
- the heat sink 50 has a cutout 51 in which the connecting element 16 is arranged to engage.
- the heat sink 50 preferably has engagement elements which are designed for fastening the light emission arrangement to the housing 10.
- engagement elements which are designed for fastening the light emission arrangement to the housing 10.
- a screw connection can be provided here.
- the heat sink 50 also preferably has openings which form continuations of the light openings 8.
- Fig. 13 A variant is shown in which the light guide element 7 has an integrated screw bushing 55 for connection to the housing 10.
